INTRODUCTION

The purpose of Volume One of the “Planning & Engineering Design Standards (PEDS) Manual” is to communicate to developers, architects, engineers, and other design professionals, the City’s design standards and development expectations for the many and varied land uses in the City of Surprise. The Planning Design Standards are not intended to be viewed as the only solution, but as the baseline for the minimum design expectations necessary for development approval by the City. These design standards are preferred approaches, but alternative solutions that achieve expected protection of existing neighborhoods and the native desert setting may be proposed and considered. The intent is to ensure the creation of smartly designed, sustainable, compatible, quality development that enhances the livability and desirability of the City of Surprise.

The Standards identify key site design and architectural elements, streetscape, right-of-way and on-site landscaping, and connectivity and multimodal aspects that are important to the City while providing latitude for creative, innovative solutions to design proposals. The basic nature of these standards affords the necessary flexibility to permit creativity and innovation, which the City encourages, as new technologies, techniques, and products become available as well as to accommodate difficult or unusual site design situations. However, the following Planning Design Standards and all appendices herein are formally adopted in Chapter 107 of the Land Development Ordinance (LDO) and therefore have the full force and effect of law.

Some land uses will be more auto-centric than others, but in all cases an objective is to balance vehicular access with those of alternative modes such as pedestrians, bicyclists, transit/bus, and the potential for commuter/light rail in the future.

In addition to ensuring quality development, these Planning Design Standards are intended to implement the Surprise General Plan 2035 by:

Increasing pedestrian and multimodal connectivity;

Promoting energy efficient and environmentally sensitive designs;

Creating sustainably built environments;

Providing quality development with compatibility between developments;

Diversifying development in a manner that enhances the value of property;

Encouraging distinctive development that reinforces Surprise’s “sense of place”.

The following Volume One Planning Design Standards work in conjunction with the Engineering Development Standards found in Volume Two to constitute the Surprise PEDS Manual. Words or phrases expressed using italics shall assume the meaning as ascribed in Appendix A herein.

PEDS Vol 1: Planning Design Standards


CHAPTER 1: STANDARD REQUIREMENTS FOR ALL LAND USES

1.1 GENERAL LAND/SITE DESIGN & DEVELOPMENT

A. Existing features of the site, including but not limited to, rock outcroppings, steep slopes, washes, and views of the surrounding mountains shall be incorporated in the planning and design of the development to shape the identity and character of both the development and the open space component to the greatest extent possible.

B. Sustainable development practices shall be followed when planning the design of any proposed project regardless of it physical location within the City of Surprise. In addition, the provisions and standards found in Chapter 5: Environmentally Sensitive Lands Standards herein and the regulations in Article2, Chapter 104 of the LDO shall be followed for any proposed project on property that possesses cultural resources and/or environmentally sensitive features.

C. If a development parcel is located adjacent to or encompasses areas identified as open space, trails and greenways, in either the Surprise General Plan or Parks and Recreation Master Plan, the development shall be required to provide for and incorporate those areas into the overall site design and the open space network of the development. Conservation of these identified community-wide open spaces, trails, and greenways and construction of the improvement within them shall be the responsibility of the developer. These larger community-wide trails shall be platted as a “multi-use trail easement” and stated to allow for public use and access, with maintenance responsibilities falling onto the Homeowners’ Association, unless those open spaces, trails and greenways have been dedicated to and accepted by the City of Surprise into the City park system for maintenance responsibilities.

D. The open space component of a new development shall tie to the City’s broader multimodal system, open space system including washes and wildlife corridors, and ultimately to the hierarchy of parks planned throughout the City.

E. The development’s pedestrian circulation and open space system shall provide for connections to adjacent developments to enhance continuous multimodal circulation and open space throughout the City of Surprise. These spaces shall be large enough to also serve as a buffer between incompatible land uses, different development densities, and different development patterns.

F. All new dry utilities must be placed underground; with the exception of wireless facilities (WF) and 69 KV or larger electric lines.

1.2 OPEN SPACE DESIGN

A. The amount of required open space for any development is based on the zoning of the property and further outlined in Chapter 104 and Chapter 106 in the LDO. Different kinds of open space serve different needs (for example, ecological, recreational, entertainment, and culture). While some open space may serve more than one need, there is a particular need to retain natural desert open space and corridors.



B. The required open space shall be designed, located, and oriented according to the following:

1. Conservation of the Sonoran Desert vegetation and wildlife habitats that are important to native wildlife species and create a “sense of place” for the community.

2. Individual development parcels that provide opportunities for hiking, cycling and equestrian trails that are safely and conveniently located and provide bicycle racks, benches and/or other amenities that promote their use.

3. Provide physical connections to adjacent parcels that enhance a structure of continuous open space, streetscape, and a multimodal circulation system. Utilize and enhance existing access easements along the CAP canal with additional five- to ten-foot (5’-10’) tracts for trails and open space with parallel ROW, limiting backyards/walls distances to less than eight hundred feet (800’).

4. Preservation and/or enhancement of watersheds, major drainage ways, wildlife corridors, cultural resources, and natural desert open space view corridors to the surrounding mountains.

5. Include on-site storm water retention facilities as an integral component and useable amenity of the open space network. Plan the site’s drainage to lead runoff away from active use areas, pathways, and parking areas while utilizing a Low Impact Design.

6 Wherever and whenever possible, orient open space for optimal solar access to extend its use throughout the year. Provide user-friendly gathering and rest areas that are shaded, landscaped, lighted, and furnished to invite and encourage use by the public.

7. Maintain appropriate buffer areas and/or setbacks between wildlife corridors and developed areas to mitigate edge effects on wildlife corridors.

8. Maintain connectivity to other community and regional parks, trails and greenspaces.

9. Provide for wildlife permeability within open space corridors and across restrictive sections of major roadways and other potential barriers.

C. In addition to the undeveloped buffer areas, the preserved environmentally sensitive features, and/or cultural resources the following amenities and infrastructure designs are examples of areas/elements that can also be calculated as open space for the purpose of meeting the open space requirements for the specific property:

1. Existing desert washes and wildlife corridors if:

a. they are incorporated into the overall open space design of the development in their historical unaltered location; and



b. the buffer area adjacent to such wash/corridor is improved with a multi-use pathway for bicycles, pedestrians and if applicable equestrians.

2. Usable open space such with amenities as outlined in Chapter 2 of the PEDS such as landscaped or hardscaped plazas, wide landscaped tracts at ends of residential blocks, and gathering and sitting areas designed to provide an open park like atmosphere;

3. Community gardens;

4. Protected bike lanes within the right-of-way and multi-use pathways outside of the right-of-way (not sidewalks associated with the street right-of-way);

5. Retention facilities if:

a. given a “natural” character (not ditch-like in design) by terracing, berming, and contouring to naturalize and enhance the aesthetics of the basin and constructed with/of natural materials (not concrete lined); and

b. landscaped and connected into the overall open space system in a manner that could accommodate amenities as outlined in Chapter 2 of the PEDS.

6. If the developer chooses to utilize the Alternative Local Street cross section (see Illustration 1A) in lieu of the Standard Local Street cross section (see Illustration 1B) then the entire landscape strip may be calculated as open space even though the landscape strip is within the public right-of-way. The excess landscape strip must exceed standards by a minimum of five (5) foot for open space credit to apply.

A. ROADWAY DESIGN.

1. The road system shall be designed to permit the safe, efficient and orderly movement of vehicles, bicycles and pedestrians; meet the needs of present and future populations served; have a simple and logical pattern; respect natural features and topography, promotes street life and activity and; present an attractive streetscape.

2. There shall be no development of roadways built to freeway, highway, or parkway standards unless and until that roadway and roadway alignment is shown in the Roadway Systems Element of the Surprise General Plan 2035 as a proposed roadway; unless an amendment to the General Plan is approved.

3. All proposed public rights-of-way shall be developed with interconnected streets, sidewalks and pathways to accommodate multimodal travel and comply with ADA requirements. Travel modes may include but are not limited to, vehicles, Neighborhood Electric Vehicles (NEV), pedestrians, bicycles, public transit and, where appropriate equestrian.

4. All parkway, arterial and collector streets shall be designed with on-street bicycle lanes, a minimum of five feet (5’) in width.

a. Parkway and arterial streets shall provide protected bike lanes.

b. The collector streets may use striping to delineate the on-street bike lane.

5. All parkway, arterial and collector streets shall separate vehicular traffic from pedestrian uses by utilizing detached sidewalks that create a landscape strip. The landscape strip should be designed to allow landscape plantings, including but not limited to street trees, and in a manner that utilizes LID design for watering. Plant material should not impact either the drive lane or the sidewalk with low overhanging branches or root upheaval. For arterial and collector streets the sidewalk typically will run parallel to the street with the landscape strip between curb and sidewalk being between eight feet to sixteen feet (8’-16-) in width for the specific type of street per the Engineering Development Standards outlined in Volume Two.

6. Collector streets shall be designed to the street widths necessary to serve the planned intensity and density of land uses, the number of average daily trips generated by those uses, at the appropriate service level acceptable to City, as demonstrated by the required Traffic Impact Analysis (TIA).

7. All existing and proposed street alignments and connections shall provide direct routes to local destinations such as neighborhood commercial centers, schools, parks and other common destinations in order to: encourage greater use of streets by pedestrians and cyclists; eliminate concentration of traffic on just a few roads; and avoid the use of



overly circuitous street layouts and cul-de-sacs, unless physical site constraints require modifications to the connections and alignments.

8. The intersection of two (2) streets shall be at right angles with one another; except when constrained by topography and approved by the City Engineer.

B. CUL-DE-SAC DESIGN.

1. Cul-de-sacs may be permitted only to accommodate specific site conditions, such as natural topographical constraints when all other design options have been exhausted.

2. When adjacent to a parkway, arterial, collector road, community trail, or regional drainage corridor a cul-de-sac shall be designed so that the bulb end provides a minimum thirty foot (30’) wide landscaped open space tract that directly connects the cul-de-sac to the parkway, arterial, collector road, trail, or corridor. This open space area shall be designed with a paved walkway/trail to allow pedestrian and bicycle access to the larger community circulation and/or open space systems. (see Illustration 3).

C. MULTIMODAL/MULTI-USE PATHWAY DESIGN.

1. The pedestrian network in all new development shall consist of both:

a. Sidewalks that provide continuous direct routes and connections internally to neighborhood parks and externally to adjacent arterial and collector streets to provide safe routes to places where people want to go - including homes, schools, parks, recreation, third places and neighborhood shopping areas, public services, and transit.

b. Multi-use pathways (associated with the open space and greenways) designed to accommodate pedestrians and cyclists, and where necessary equestrians, that are an integral component of the open space system and that facilitates the interconnectivity to different neighborhoods, adjacent developments, and the larger community and regional pathways and open space systems.

ILLUSTRATION 3

Provide landscaped open space and connectivity by opening the subdivision perimeter fence at the end of abutting interior cul-de-sac streets.

Arterial &/or Collector Street Community Trail, or Regional Drainage Corridor



2. Developments that either contain, are adjacent to, or can directly connect to a Community and/or Regional Trail/Path, as shown in the Surprise Parks and Recreation Master Plan, shall both design the pedestrian and bicycle trails/paths as outlined and provide the minimum easements as delineated in the said Master Plan. Equestrian trails shall also be considered; where appropriate and adjacent to the “Regional Path” as shown on the Surprise General Plan 2035 and the Surprise Parks and Recreation Master Plan.

3. Where multi-use pathways cross arterial streets, the pathway shall comply with ADA requirements and include safety measures; such as bicycle and pedestrian activated signals, median refuges, warning signs for both motor vehicles and pathway users, special street markings or striping, and barrier posts (“bollards”) that are spaced widely enough to permit cyclists and wheelchair user’s easy passage but prevent motor vehicle access (see Illustration 4 below).

4. A multi-use pathway shall be designed to be, at a minimum, ten feet (10’) wide for two-way pedestrian and bicycle movements. The pathway may be either a single or split pathway provided there is a minimum hard-surface width of five feet (5’) for pedestrians and five feet (5’) for bicycles and skaters.

5. Multi-use pathways shall be placed within tracts or public use easements and located outside of the public right-of-way to provide pedestrians, cyclists and other users’ alternate means of moving throughout the development via a complete and continuous separation from vehicular traffic. Where the pathway is adjacent and parallel to the roadway a minimum ten foot (10’) wide landscaped landscape strip shall be provided to separate the street from the pathway (see Illustration 5 below).

6. Where pathway corridors are also designed for use by equestrians, the minimum width of the total pathway right-of-way, including a minimum landscaped area of ten feet (10’) shall be twenty-seven feet (27’), with the additional five foot (5’) portion devoted to equestrians constructed of a softer surface consisting of stabilized decomposed granite, aground

Special markings shall be required where pathways intersect major arterial streets.

gravel or other compatible dense, yet soft material (see Illustration 5 below).

7. Under-crossings for multi-use pathways shall be well lit and designed to provide a minimum width of fourteen feet (14’) and a minimum overhead clearance of ten feet (10’).

8. When equestrian paths are designed they may require additional standards.


A. GENERAL LANDSCAPE STANDARDS.

1. Xeriscape methods and low water use drought tolerant plants shall be utilized within all public rights-of-way, public spaces, and landscaped areas associated with all surface parking lots; the plant list for such public spaces is Appendix B in PEDS Volume 1 herein. The City’s preferred plant list for homeowners associations/property associations for private development open spaces, buffer areas, and the individual homeowner’s on-site use is Appendix C in PEDS Volume 1 herein.

2. All landscape areas shall be supplied with an efficient irrigation system. Introduced landscape materials shall consist primarily of durable species tolerant of soil compaction, and requiring minimal irrigation, fertilization and maintenance (see Appendix B and Appendix C herein).

Illustrative Example: Multi-use pathway parallel to a roadway.

12’ min.



3. The landscape design should strive to visually create a larger massing of a single color groundcover and/or shrub with an accent color rather than being seen as a number of individual plants.

4. The use of turf shall not be allowed in any public rights-of-way. The use of natural turf outside of the public rights-of-ways shall be limited to twenty percent (20%) of the total landscaped area; excluding artificial turf and designated turf areas on a single family lot, when required in retention basin, within public parks, and golf courses.

5. Retain native trees and cacti and incorporate it into the project unless determined to be unsalvageable by a licensed landscape professional (refer to Chapter 107 of the LDO).

6. Any landscape design in the City of Surprise shall comply with the provisions of the city’s Water Conservation regulations (Chapter 58; Article VII) and in particular the specific limitations regarding the use,

design, location and installation of fountains or water features.

7. Landscaping maintenance of the center medians within those streets classified as Parkways and Arterial streets shall be the responsibility of the City of Surprise after acceptance.

8. Additional standards for Neighborhood Developments, Commerce, Office and Mixed-Use Developments, and Business Park and Industrial Developments may be found respectively in Articles 2, 3 and 4 herein. Additionally, adherence to the landscape regulations in Chapter 107 of the LDO shall be required.

B. GENERAL STREETSCAPE STANDARDS.

1. Landscape medians within the right-of-way shall utilize “Low Impact Development” methods to capture first flush stormwater, refer to Section 1.6 herein and meet the requirements of Volume Two Engineering Development Standards; Chapter 8 of the PEDS.

2. To encourage high pedestrian usage and reinforce the community’s multimodal circulation system the street rights-of-way shall incorporate landscaping, outdoor lighting and, when determined by the City, appropriate streetscape furnishings along arterial and collector roadways. (See Illustration 6 below).




A. High quality “stylized” or “theme” architecture i s permitted, as long as it incorporates the architecture of the area and maintains continuity with the community as a whole.

B. Buildings shall be designed and oriented to minimize heat gain and maximize pedestrian shade opportunities; including materials, elements, and details (i.e. extended or cantilevered roof eaves, thickened building walls, awnings).

C. The City strongly encourages all new buildings to meet Leadership in Energy and Environment Design (LEED) certification standards; and building sites and development in general to utilize Low Impact Development (LID) technologies.

D. All exterior elevations shall provide architectural detailing (360° architecture) by the consistent use of color, patterning, finish, type and application of materials, and the wrapping of materials around onto adjoining walls of the structure to provide design continuity and a finished appearance to the building.

E. Flat monolithic facades and large unvaried rooflines are not permitted. The building façade shall utilize recessed entryways and windows, groupings of windows, horizontal and vertical offsets and reveals and three-dimensional detail between surface planes, to create shadow lines and break up long continuous flat wall areas.

F. The use of architectural features such as three-dimensional cornice treatments, enclosed parapet wall forms and details, and overhanging eaves shall be utilized to enhance the architectural character of the roof.

G. Solar panels located on rooftops shall be placed consistent with roof pitch, and sized to appear as an integral part of the overall roof design. The solar panels may be used as the roof structure itself (e.g. carports, shade structures, patio covers).

H. When appropriate to the style of a building, a variety or combination of roof forms are preferred as a means of adding visual interest and diversity to the City’s “roof horizon” and to avoid the “sameness” of roof styles. The typical roof types are gable, hip, flat, shed, gambrel and mansard style roofs as shown in Illustration 7.

1.6 GRADING & DRAINAGE DESIGN AND FLOODWAYS

A. Washes and drainage patterns shall be maintained in their historic location. Mass grading of parcels over five acres (5 ac) in size shall require additional approval from the Community Development Director; phased grading of a development is the preferred method. The grading concept for any site shall be a balanced cut and fill on the site to limit damage to the natural topography; except in the case of approved and permitted mining activities.

B. Low Impact Development (LID) construction methods to meet the needs of both on-site and off-site stormwater drainage , such as but not limited to, bioswales, bioretention planters, and strategic use of water features shall be implemented to both improve stormwater management and enhance the built environment of the development (see Illustration 8 below).

C. In the event that retention basins are required, per the drainage analysis, they shall be designed as landscape features rather than large, plain depressions in the site. To the greatest extent possible, basins shall be located and oriented to connect with other open space areas of the development which in turn connect physically, functionally, and visually with open space in adjoining developments/sites.

D. Design any water harvesting approaches to supplement landscape irrigation, reduce stormwater discharge, and downsize retention facilities.

E. Where a floodway or wash traverses a development site, the floodway or wash shall be set aside as open space and improved using environmentally sensitive channel and bank stabilization techniques to provide a naturally appearing restored, enhanced and stabilized floodway or wash. Under no circumstance shall the channel or sides of a floodway or wash be paved over in concrete or similar material (see Illustration 9).

6. All buildings shall harmonize architecturally with the residential character of the neighborhood as determined by the Community Development Director or designee.

D. MODEL HOME COMPLEX

1. Guidelines:

a. Seventy-five percent (75%) of plans constructed in a model home complex must be "non-garage dominant".



b. If any approved product line consists of one plan that provides a significantly recessed garage, that plan must be modeled.

c. If any approved product line consists of two or more plans that provide a significantly recessed garage, the number of those plans modeled will be determined by the city manager or designee.

2 Site standards:

a. Site design shall comply Sec 106-10.29 of the LDO.

b. Landscapes for model home complexes shall comply with the PEDS and Chapter 107 of the LDO.

3. A "zero-step" entrance shall be required for all model homes within the City of Surprise.

a. "Zero-step" entry shall have a floor or landing on each side of the primary entrance door. Such floor or landing shall be at the same elevation on each side of the door. Landings shall be level, except for exterior landings, which are permitted to have a slope not to exceed 0.25 units vertical in 12 units horizontal (two percent). Thresholds for such doors shall not exceed one-half-inch in height, and thresholds with changes in level greater than one-quarter-inch shall be beveled with a slope not greater than one unit vertical in units horizontal.

b. The city manager or designee may waive the requirement "zero-step" entry if it is found that it would prove to be cost prohibitive. Such cases however, the builder must still provide a zero-step entry into at least one model home and an ADA compliant pathway to all models.

c. Model signage. All new model homes and sales areas shall include signage that read - "Ask Us About Accessibility Options."

d. Education. An educational DVD shall be available to sales staff and potential homebuyers regarding the benefits of visitability.

E. ADDITIONAL BUILDING TYPES IN TND DEVELOPMENTS.

1. In order to create neighborhoods of blended densities; to provide a broad choice of housing types for lifelong livability and a diversity of needs; to promote walkability; and to enable appropriately-scaled and well-designed compatible land uses it is important for the TND to consider building types other than what might traditionally be expected.

2. The following four (4) types of housing products shall only be permitted in conjunction with the Traditional Neighborhood Development (TND) Zoning District (see Chapter 106, Article 4 of the LDO):



a. Shared Court: This design consists of a 4-5 of detached dwellings arranged to a defined shared auto court that is typically perpendicular to the street; known as 4-packs and 5-packs (see Illustration 12 below).

Specifics: (minimum 10,000 SF lot)

4-5 attached or detached units

(1,600–1,850 square foot each) possible.

Two units face the public street, gives appearance of two single-family homes from street.

As shown would require condominium ownership. With modifications, may also be possible with units on separate lots oriented toward the shared court as a private street tract.

Arranged around a shared driveway with special paving that provides both vehicle and pedestrian access. Single access point allows up to 4 off-street parking spaces.

ILLUSTRATION 12 - Shared Court



b. Shared Cluster: The shared cluster takes the place of a private rear or front yard and becomes an important community-enhancing element for this product type. This product type is appropriately scaled to fit four (4) units on an individual lot of ten thousand square feet (10,000 sf) or more. (See also Illustration 13 below).

c. Mansion Apartment: This building type consists of a minimum of 4 side-by-side and/or stacked dwelling units with one shared entry. This product type has all the appearance of a medium-large sized single-family home and is appropriately scaled to fit on an individual lot size of ten thousand square feet (10,000 sf) or more (see Illustration 14 below).

d. Rowhouse/Townhouse: This building type is a small to medium sized, typically attached structure that consists of 4–8 rowhouses placed side-by-side that front to a public street. This type may be appropriate in a location that transitions from a traditional detached single-family neighborhood into a higher density, mixed use, neighborhood core (TND), or a transit-oriented development (TOD) land use with the appropriate scale to fit on an individual lot of four thousand square feet (4,000 sf) or more. (See Illustration 15

below).

Specifics: (minimum 10,000 SF lot) 4 units (1,500–1,950 square foot each)

Arranged around a common green, either attached or detached.

Intended to allow fee simple ownership, with common green held as a common tract.

Massing of front units reflects neighborhood patterns of houses on 50' wide lots.

ILLUSTRATION 13 - Shared Cluster



E. NON-RESIDENTIAL BUILDINGS IN THE NEIGHBORHOOD LAND USE.

1. Non-residential structures shall be designed to create transitions to the surrounding residential development with the size, massing and height of the structure relating to the prevailing scale of the adjacent residential neighborhood.

2. Taller buildings shall be made to appear less imposing by stair-stepping building heights and rooflines back from the property lines, breaking up the mass of the building, providing a broader open space/landscape area as foreground for the building, and providing a building frontage presence to the neighborhood street rather than a parking lot frontage.

3. Assembly Uses may be required to provide a traffic study, depending on the specific location.

2.6 EDGE TREATMENT AND TRANSITIONS

A. EDGE TREATMENT.

1. No transition or buffer area shall be required if a new development that directly adjoins/abuts an established residential neighborhood is of the

Specifics: (minimum 10,000 SF lot)

Min of 4 units (1,000-1,400 sq. ft. each; not including garages)

One shared main entrance area off front porch. Unit division from within structure.

Street frontage designed to reflect appearance and scale of a single-dwelling house to blend with neighborhood context.

ILLUSTRATION 14 - Mansion Apartment

Specifics: (minimum 4,000 SF lot/DU)

Consists of 4–8 rowhouses placed side-by-side that

Front to a public street

same density and provides lot sizes that are approximately the same size as the existing neighborhood.

2. New residential development proposed for the edge of the urbanized area of the City shall buffer and transition from existing adjacent agricultural or rural developments. Any increased density shall be designed inward onto the new project and/or along the shared urbanized edge.

a. Buffer the existing established neighborhood using a landscaped open space tract that is a minimum of one-hundred feet (100’) in width along the perimeter between the two neighborhoods (see Illustration 17 below); and

b. The open space buffer area shall be designed in a manner to connect to the open space, pedestrian and trail systems within the new development and in a manner that will further accommodate future connections from other adjoining developments as urbanization occurs.

c. The buffer area shall be preserved for perpetuity as either a tract or easement, allows public use and access, and calculated as part of the development’s open space requirement.

3. When a new development of higher density proposes to only be separated from an established lower density or rural residential neighborhood by a “residential local” street the new development shall provide a landscaped buffer, a minimum of fifty feet (50’) in width, adjacent to the shared local street plus a single row of lots, which are no smaller than one-half the average lot size of the adjacent existing rural neighborhood lots (see illustration 18 below).

Existing Agriculture - Rural

4. New residential developments that directly adjoin /abut a planned or existing open space, trails and greenways area, as designated in the Surprise General Plan or Parks and Recreation Master Plan, shall utilize an open style of perimeter fencing rather than a solid or view obscuring perimeter wall along that specific edge of the development.

5. New residential development proposed in those areas that abuts one of the three (3) Employment Character Areas of the City, as shown in the General Plan, shall be responsible for providing the buffer and transition area from the employment character area and not the other way around. The use of appropriate landscaped buffering, lot orientation, stepped building heights, and street design should be utilized in close proximity to these designated areas.

B. ADDITIONAL EDGE TREATMENT STANDARDS FOR TND DEVELOPMENTS.

1. The exterior boundaries for a TND development shall be designed in a manner that provides fifty percent (50%) of the frontages to the greater community that are something other than typical privacy perimeter walls, including but not limited to, open space areas, civic space land uses, mixed-use and multi-family land uses.

2. Residential development parcels, within the TND development, that have home sites backing onto the exterior boundaries of the TND development along public rights-of-way shall provide both a decorative privacy wall and then a landscaped open space tract, a minimum of thirty feet (30’) in width, outward towards the greater community along said exterior boundary.

New Higher Density Neighborhood



3. If residential lots are platted directly adjacent to an existing residential neighborhood or a vested but undeveloped residential parcel (outside the TND) then those TND lots shall provide a lot size not less than one-half (½) the size of the existing or proposed adjacent lots as applied to the lot line that borders the existing or vested residential parcel(s) except if lots are separated by a street or open space buffer area that is at least one hundred feet (100’) in depth.

C. TRANSITIONS.

1. Buildings located along the exterior edge of new master plan projects, adjacent to undeveloped land or existing rural development shall either maintain a low profile in terms of height, bulk and massing or increase the width of the buffer area between the two (2) different intensities of use by a distance equal to the proposed building height.

2. Grade changes from the off-site grades along the perimeter of a new subdivision shall be minimized and lots in the new subdivision shall not be more than eighteen inches (18”) above or below the abutting lots in the existing subdivision. If a greater grade change is desired or necessary, there shall be a buffer or a gradual grade transition on the new subdivision in order to minimize the change at the property line.

D. SCREENING.

1. In order to promote a more “visually friendly” and open community, the construction of long, unbroken and monotonous expanses of six foot (6’) high, solid fences and stucco walls around the perimeter of new single and/or multi-family residential developments is strongly discouraged. If perimeter walls are provided, they shall be designed to include: changes in the surface plane of the wall or fence; variable heights; articulated recesses and wall offsets sufficient in depth to permit landscaped pockets for the planting of significant clusters of mature trees and shrubbery. (See Illustration 19 below)

2. Walls and fences shall be kept as low as possible and be designed to blend with the site’s architecture through the use of similar materials and colors.

ILLUSTRATION 19



2.7 RESIDENTIAL SOLID WASTE GUIDELINES


1. All solid waste collection routes shall meet engineering design criteria (street width and turning radii).

2. Residential refuse/recycle collection. Solid waste collection vehicles require free and clear access to street right of way and clear curbside access to residential solid waste containers placed out for service on designated day of collection. In addition, solid waste collection vehicles require collection routes shall be designed so that collection vehicles can safely access and lift containers without obstruction. (ground or aerial).

3. Solid waste vehicles require 44’ – 0” outside turning radius and 28’ – 6” inside turning radius. (see detail)

4. Solid waste collection vehicles are approximately 30’-0” long and can weigh up to twenty-nine (29) tons when fully loaded. Collection routes must be engineered to support collection vehicles.

5. To maintain the safety of the site, solid waste vehicles shall not be required to back up more than fifty feet (50’) when or after servicing a trash/recycle container.

6. The collection route must be designed such that, collection vehicles shall travel through a site without back tracking or making u-turns.

7. No building, awning, or fixed structure projections shall be allowed in the route of the solid waste collection vehicle. Residential collection requires a minimum overhead clearance of sixteen feet (16’) from the right of way, and a minimum of two feet (2’) behind the collection container and/ or sidewalk, is required along the route curb line.

8. Routes shall be clear of all obstructions at the curb, to include walls, overhead wires, awnings, and other fixed objects.

Show all container locations, with addresses on site plan, for visibility triangle, refer to latest version of engineering and design standards.

2. Designated container location may be signed “no parking on trash days”. There should be fifteen feet (15’) of space from the start of the no parking area to the first container. Containers should have a minimum seventy-eight inches (78”) spacing center to center of container. There should be fifteen feet (15’) of space from the last container to the end of the no parking area.

3. Placement designations will not be located near cluster mailboxes.

4. The required use of identified locations should be included in the homeowners conditions covenants, and restrictions.

5. Designated container locations will also be used for bulk collection for each unit.



CHAPTER 3: COMMERCE, OFFICE, AND MIXED USE LAND USES

3.1 GENERAL LAND/SITE DESIGN AND DEVELOPMENT

A. GENERAL BUILDING SITE DESIGN.

1. Limited residential land uses may be permitted in the Commerce and Office Character Areas as shown in the General Plan; in which case development patterns shall provide for higher street connectivity, smaller block lengths, and improved transit options. When developed, residential land uses must be zoned mixed-use (MU), high density residential (R-3), or be part of a TND development, and located along and oriented toward a proposed or existing collector or arterial corridor where direct access to transit is available or will be provided over time.

2. The project design, including the building location and orientation, shall incorporate and benefit from the desirable local elements (e.g. winter sun, mountain views, and even stormwater for irrigation) and to deflect unwanted elements (e.g. noise, summer sun) regardless if the development is a conventional single structure building, freestanding as “pad” sites and/or “in-line” buildings within a commercial center, outdoor recreational facilities, or parking structures.

3. Building(s) shall be designed in a manner to take advantage of the connection to the greater community open space system. Appropriate linkages (i.e. double building frontages, outdoor seating and dining spaces, walkways, common landscape areas, plazas, and unfenced property lines) shall be considered to further encourage a multimodal connection to the site and the use of the public open spaces as a transitional element.

4. Community/regional commercial development, office, institutional, mixed-use, and civic/cultural land uses shall be located adjacent to and oriented toward major arterials, public transportation routes, and the community’s multimodal circulation system when applicable.

5. The building(s) shall be visually if not physically linked to both the on-site parking lot as well as to the public street by way of a designated walkway to safely and conveniently move pedestrians as they use the development. These pedestrian connections shall provide relief from the sun through the use of shade trees, arbors and other shade techniques that may prove acceptable to the City. These pedestrian connections may be constructed using a type of permeable pavement.



6. A corner building shall have a strong frontage “presence” at the setback lines for each street. This “presence” requirement may be accomplished through angled or sculpted building corners, providing an open plaza, outdoor patios, display (not storage) areas, and seating areas that further encourage and add to the pedestrian environment at the street (see photo examples below).

7. Undeveloped pad sites/phases of a development that have been disturbed in any manner shall be required to install dustproof ground cover ahead of the construction phase schedule to prevent the intrusion of unwanted dust or blowing debris from the site/lot.

B. MULTIPLE BUILDINGS SITE DESIGN.

1. When a development has multiple buildings (e.g. office complexes, commercial centers, mixed-use/residential etc.) the buildings shall be designed as groups or integrated clusters rather than designing them in-line, as stand-alone buildings, or pad sites. The way these buildings are grouped or clustered should further define and create an outdoor room of open space for either active or passive uses, including but not limited to, plazas, courtyards, gathering areas. The resulting open space area should allow for extended shop fronts, outdoor dining, and entertainment areas at the edges of this open space/plaza area.



2. All large scale retail centers and commercial office centers shall provide a pedestrian oriented design with sidewalks, seating, trees, lighting, and pedestrian scale signage. At least one outdoor gathering space/open space, that provides amenities, including but not limited to, seating, shade, lighting, and heating for year-round use, shall be provided for every one hundred and fifty thousand (150,000 sf) of developed floor space or fraction thereof.

3. As a center of pedestrian activity, plazas in multiple building commercial, office, and mixed-use developments shall provide adequate seating in the form of benches or low seating walls in addition to any seating areas that may be provided in association with dining areas.

4. Plazas, including their entrances and exits, shall be illuminated in a manner that facilitates natural surveillance opportunities and discourage unsafe activities. All lighting in plazas shall adhere to the lighting standards in Chapter 107 of the LDO.

C. ADDITIONAL STANDARDS for TND DEVELOPMENTS

1. The commercial development within the TND shall be designed with interior oriented parcels for the development of a “neighborhood core” to first serve the TND and secondly serve the wider community. The neighborhood core is intended for smaller scale pedestrian oriented retail, service, mixed-use, and public facility/civic space uses that provide opportunities to create third places and serve the daily needs of the residents within the TND development.

2. The neighborhood core and other commercial parcels shall be integrated into the TND by providing:

a. prevalent pedestrian connections to the TND pathway system and adjacent residential parcels; and

b. gathering spaces and outdoor areas that connect the commercial spaces to the open space network and the TND pathway system (other than sidewalks along the street system) of the TND; and

c. compact design and spatial organization of the commercial buildings that are walkable and inviting by providing seating and shade; and

d. multimodal use of right-of-ways and incorporation of streetscape and amenities that enhance the pedestrian activity level of the street; and



e. vehicular connection internal to the TND that does not require access via an arterial street outside of the TND development.

3. As part of a mixed use development, residential uses are encouraged as a vertically integrated use within commercial buildings both within the residential neighborhoods and in the neighborhood core setting.

4. The horizontal integration of different and mixed land uses, particularly within the neighborhood core, shall be compact and interconnected through the pedestrian space; utilizing the hardscape area between uses and buildings for extended shop fronts, outdoor dining, entertainment and outdoor gathering areas, information kiosks, mobile carts, and other street related activities.

5. Live/Work units (occupant owned business) are encouraged when allowed.

D. SCREENING.

1. Trash and refuse collection containers shall be screened with a six (6) foot decorative masonry wall. Trash and refuse containers shall be located such that they are not the visual focal point of a driveway or parking area, or cannot be viewed from a public street. Projects which provide on-site daily management and maintenance personnel (i.e. service stations and convenience markets), and those sites that can only locate the refuse containers in a highly visible location shall provide decorative latching gates, for screening the containers, at the opening to the enclosure.

2. Equipment such as, but not limited to, vending machines, collection bins, newsstands, and shopping cart corrals shall be placed in an area designed for their use. These uses shall be screened and situated in a manner so as not to block vehicular or pedestrian traffic, reduce any required parking, block the sidewalk, or become a focal point for the development.

3. Outside storage areas, work areas, and production areas shall be screened from the public street view and adjacent residences, mixed-use, office, and other commercial uses with a minimum six feet (6’) high decorative masonry wall; except for the living plant materials areas associated with an outdoor landscape/garden center which may use non-masonry fencing. Non-plant materials shall not be stacked, piled, or stored in such a manner as to project above the screen wall.

4. Building site details related to utility boxes, transformers, generators, chiller farms, mailboxes, and air conditioning units shall be integrated into the overall design of the building and/or development and screened from public view, yet remain accessible for servicing.



5. Mechanical equipment and similar utility devices, whether ground level or roof mounted, shall be screened from public view and architecturally designed to appear as an integral part of the building; except for solar panels. The mechanical equipment screening shall be included in the overall building height. Mechanical equipment shall be treated to be non-reflective. Electrical meters, service components, and SES cabinets shall be screened from public view and designed to appear as an integral part of the building.

6. Electrical transformers, backflow prevention devices, large water standpipes, telephone panel boxes and any other obtrusively large electrical or mechanical device that is installed as a part of, or results from, a new development project shall be located to the rear of the project site; and screened from public view through the use of landscaping and/or screening walls. If new installations require locations at the front of a development site or where such devices currently exist at the front of a site, they shall be screened by substantial landscaping, an architectural barrier, or an artistic wrap to blend or match the existing environment.

7. No deliver or loading dock, mechanical trash compacting equipment, or service loading bay (automotive service, tire, etc.) shall be located in a manner that will cause them to front onto the development entry drive, or onto a major or minor arterial roadway. These items shall be located in the least obtrusive manner, preferably on a less prominent and visible side of the building and shall be adequately screened from public view.

8. Parking areas adjacent to the required setback from right-of-ways shall be screened from public view and from adjacent residential properties by a solid three foot (3’) high screen wall that is decoratively treated to match the architectural style and design of the development or a landscape berm or combination thereof.

9. Boundary line fencing along the common property line shall be required when the development is abutting a single family residentially zoned property. This wall shall be a solid decorative masonry wall limited to six feet (6’) in height; unless otherwise indicated on the LDO. A multimodal pathway connection shall be required from the residential neighborhood into the commercial development whenever the adjacent residential development can accommodate such access point.

10. All masonry walls intended for screening functions shall have an architectural texture, color and finish compatible with the primary building.

E. PARKING DESIGN.

1. Private parking lots for commercial and office uses that are adjacent to one another, but operate under separate property ownership, shall to the greatest extent possible, be designed and located contiguously to each other, provide for prominent drop-off points for ride sharing, and have shared and reciprocal access and an internal circulation system that



provides for the safe and efficient internal site movement of motor vehicles, pedestrians and cyclists from one property to another without having to re-enter the street serving the developments.

2. Off-street parking serving large multi-use commerce centers, mixed-use projects, and office complexes are encouraged to provide shared parking facilities in the form of underground structures whose roof tops can be developed as landscaped pedestrian plazas, as well as retail and dining uses or clustered parking pods that are heavily landscaped and integrated with the onsite circulation driveways and connected to the pedestrian and open space system (see Illustration 18).

3. Above ground parking structures shall incorporate design features such as electric re-charging stations, autonomous vehicle (AV) staging areas, and solar panel shade structures. Rather than ramped floors, the structure itself should be designed with level floors and attached spiral/ramp access structure to facilitate reuse and conversion (i.e. warehousing, commercial office space, or affordable housing units) in the future if the demand and/or need for parking decreases.

4. To maximize the business visibility from public streets, provide definition and scale to the streetscape, and establish a pedestrian rhythm to the

Plaza Over

Parking Structure

streetscape no more than fifty percent (50%) of the off-street parking for large commercial centers shall be directly visible from the primary abutting street. Rather, the off-street parking spaces shall be located in smaller parking pods and/or to the rear or side of the structures; with the structures moved closer to the street.

5. New office, commercial, and mixed- use developments that are over ten (10) acres in size and located adjacent to major arterials and transit stops designated to provide express service to the regional transit network, may be required to provide a sheltered transit stop as determined by the City in partnership with the regional transit provider.

6. Parking lots that contain over one hundred (100) spaces should be designed with traffic calming devices installed (other than speed bumps/humps) to enhance safety and to clearly indicate the hierarchy of on-site vehicular circulation consisting of major access drives, major internal circulation drives, and parking aisles for direct access to parking spaces.

7. Provide landscaped bioretention planters at the end of parking aisles and in-between parking rows, in accordance with the provisions outlined in Chapter 107 of the LDO, to provide shade for both cars and

people.

8. Utilize the rainwater harvesting technique of sloping the parking lot surfaces to direct the stormwater runoff toward these landscaped bioretention planters. The bioretention landscaped planters may be designed as: raised flow-through planter boxes; flush in-ground planter boxes; or below grade planter boxes. Use curbstop sections, formed curb with curb openings, or flush curbs to stop car tires but allow water to flow into the planting areas.

9. All walkways that traverse vehicle drive aisles shall be differentiated from driving surfaces through a change of hardscape materials, textures, or color to emphasize the conflict points. Decorative materials such as specialty pavers, permeable pavers, stamped or colored concrete should be used to clearly delineate pedestrian travel areas from drive aisles. All paving material for walkways shall be developed in accordance with ADA requirements.

10. Minimize the use of driveways and parking aisles for walking routes by combining the landscaped islands with walkways.



3.2 OPEN SPACE DESIGN AND PUBLIC PLACES

A. Open space areas shall be clustered into larger, more meaningful areas rather than equally distributing them into smaller individual areas of lesser significance.

B. The required on-site parking area shall not be calculated as open space. Those portions of the required parking lot landscaping that are also designed in conjunction with a walking route may be calculated as open space. Building setbacks, street frontage, and on-site retention areas may be calculated as open space if those areas are landscaped.

C. The pedestrian connections, plazas, courtyards, and gathering areas within and throughout the development may be calculated as open space if they are landscaped and/or shaded in some manner and provide seating, lighting, and other pedestrian amenities.

D. The use of permeable paving (such as a structural grid system or permeable pavers), designed to accommodate stormwater and reduce the heat island effect, may be considered in areas of lower traffic volume limited only to private on-site sidewalks, pathways, and plazas where the soils are acceptably permeable and a maintenance plan and property owners association is in place to maintain the permeability of the surfaces.

E. Public art is encouraged and should be in harmony with the character and scale of the open space area in which it is placed (see Section 1.7 herein for more specific guidelines).


A. When determined necessary by the City Engineer, a development project may be required to provide a Traffic Impact Analysis (TIA) prior to receiving approval. When required the TIA shall, at a minimum, discuss the ingress and egress points, the impact of commercial traffic on adjacent development, and the overall internal circulation system of the proposed development.

B. Commercial retail and office center developments that include separately leased or owned lots/pad sites or outparcels fronting on major arterial and /or collector streets shall be treated as a single development unit, and access to the outparcels shall be from the internal circulation system of the principal commercial center rather than from separate driveways and entrances located along the adjoining arterial and/or collector street and meet the Volume Two Engineering Development Standards (EDS) access management standards.

C. Access from adjacent residential areas shall be provided by incorporating wall and landscape openings with physical connections to the commercial development’s onsite pedestrian circulation system.



D. Provide locations for bicycle racks and storage areas as well as facilities that are necessary to the use of public transportation (transit stops, benches, shade, and lighting) if suggested by the TIA. Bicycle racks shall be located off of the development’s onsite pedestrian circulation system and/or near to building front entrances.

E. Proposed new major centers of employment and governmental offices shall plan and design their pedestrian walkways and bicycle paths and open space system to link directly with public transit stops.

F. New large scale commercial and civic and institutional uses shall incorporate decorative paving patterns, approved traffic “calming” devices, landscaping, streetscape furnishings, and lighting at onsite street intersections.

G. The pedestrian circulation system may also be used for other uses and activities, including informational kiosks, public art installations, and outdoor dining; provided such uses and activities do not interfere with the safety of and accessibility by pedestrians and leave a five foot (5’) clear path of travel.

H. Sidewalks shall be designed primarily for pedestrians, conform to ADA guidelines, and be as free from obstacles as possible such as but not limited to, trash bins, fire hydrants, utility equipment and cabinets, signal poles, mail drops as well as excessive overhang from automobiles parked either diagonally or perpendicularly to the sidewalk.

I. Within a Traditional Neighborhood Development (TND) the local streets and any arterial street within the “village core” shall be designed in a grid pattern to create a walkable street system that improves the overall pedestrian environment.


A. GENERAL REQUIREMENTS.

1. Design landscapes to:

a. Utilize, to the greatest extent possible, harvested stormwater; and

b. Strategically locate appropriate plantings to cool buildings and shade parking lots, plazas and gathering areas; and

c. Provide visual screens; and

d. Improve both visual and physical aesthetics.

2. When a phased commercial development abuts residential uses the perimeter landscape and fencing shall be required to be installed and maintained along the shared property lines ahead of the construction phasing schedule.

B. ON-SITE LANDSCAPING.



1. All surface parking facilities shall provide a master landscape plan that delineates mature landscaping along the perimeter of the lot, as well as throughout the interior of the lot in accordance with Chapter 107 of the LDO and with the plant palette listed in Appendix B herein.

2. Landscape should be fully integrated with the building mechanical systems such that air conditioning condensate collection may be used directly by the landscape or directed into a cistern system; and building roof drains and downspouts whether exposed or integrated within the building walls shall be directed to landscape areas adjacent to the building where it can be stored and used to irrigate the plants or infiltrated into the ground. To accommodate pedestrian traffic the use of grated drains shall be used to direct the stormwater under sidewalks that may be adjacent to the building and into the landscape areas.

3. Initiatives utilizing short term landscape treatments should be considered for vacant building and/or pad sites within a phased development to improve the visual character as well as provide interim dust and weed control.

4. Any proposed water features should be located in plazas and gathering areas and not in auto-oriented entryways. Water features, while in use, shall continuously recirculate the water. Fountains and other water features shall be located and sized according to the scale and specific use of the open space area within a development as determined by the Community Development Director; with smaller water features utilized in smaller, more intimate open space/gathering areas.

5. Trees planted within the paved area of a sidewalk or pedestrian plaza in commercial and/or office areas having high pedestrian usage shall have tree grates that are flush with the level of the surrounding sidewalk surface, and shall be located so as not to impede through pedestrian movement. Sizing of the grates shall account for the expected growth of the trees.

C. STREETSCAPE.

1. Landscaping, lighting, furnishings, and signage should be key components in the design, location, orientation and material treatment of pedestrian and bicycle paths, and their integration into the urban streetscape.

2. As part of the first phase of a multi-phased project the perimeter right-of-way improvements, such as but not limited to, landscaping and sidewalks shall be installed.

D. ADDITIONAL TND STANDARDS

1. In the civic space area and commercial areas of the TND the “public frontage” shall include trees of various species suitable to Surprise’s



natural environment, planted in a regularly-spaced lineal pattern of single or alternated species with shade canopies of a height that at maturity clears at least one story.

2. At retail frontages the spacing of the trees may be irregular to avoid obscuring shopfronts.

3. Accommodate locations for street vendors such as mobile carts, information kiosks, public art, entertainment and other outdoor temporary uses.


A. GENERAL ARCHITECTURAL STANDARDS.

1. Where these standards call for using similar materials, forms and details, in the interest of conveying a coordinated design for a development, it does not mean that all buildings should look the same within the development. Rather, it actually seeks to balance continuity and consistency with similarity and diversity. Continuity is considered achieved when a sufficient number of design variables are similar in execution (but not necessarily identically) throughout a development.

2. All buildings on the same site shall be architecturally unified. This provision shall apply to new construction, additions and remodeling. Architectural unity means that buildings shall be related in unifying elements such as architectural style, color scheme, and building materials but that does not mean identical.

3. “Big Box” stores that have outdoor storage areas and garden centers should incorporate the outdoor storage and/or garden center area into the initial architectural design of the primary building. Screening materials and colors shall be consistent with the overall theme of the building.

4. Monotonous look-a-like structures will be discouraged. Buildings shall be designed to create a visually interesting “building rhythm” by varying building form, volume, massing, heights, roof styles and site orientation.

5. Projects with more than one building or with a single building over 20,000 SF in size shall create different angles of buildings to the street to avoid monotony in site design unless other architectural treatments can achieve the desired result.

6. The development shall be designed to facilitate the efficient use of energy through building orientation, window and door placement, awnings, canopies, window treatments and other appropriate design solutions.

7. Buildings over thirty feet (30’) in height shall be made to appear less imposing by a combination of stair-stepping the building height back from the street, breaking up the mass of the building, and/or providing a broader open space/pedestrian plaza areas as foreground for the building.



8. All buildings shall provide architectural detailing on all exterior elevations (360° architecture); not just the front elevation. Window embellishments shall be provided by adding architectural features that enhance the elevations (e.g. greater variation of window design, different window styles, tile inlays and recesses, structural pop-outs, gabled roof features over the windows, etc.).

B. MATERIALS AND COLOR.

1. Subtler, less intense colors shall be used on larger, more plain-looking buildings, while the use of a greater variety and intensity of color may be appropriate for smaller structures. The use of accent colors is encouraged to provide a festive and lively streetscape. Color should be used to accent entryways and special architectural features of a building.

C. ROOF ARCHITECTURE.

1. Full roof architecture utilizing simple and varied roof forms shall be required for all new commercial, office and mixed-use development; while long, continuous mansard roofs, false mansard roofs, large expanses of flat roofs and veneer (false-front) parapets are discouraged. Parapet walls shall be designed and constructed in a manner to appear as a solid, three-dimensional form rather than a veneer.

2. Roof access shall be from within the interior of the building.

3. Green or living roofs may be considered; in efforts to absorb rainwater, provide building insulation from solar gain and heat loss, help mitigate the surrounding heat island effect, and create wildlife habitat.

4. Roof-top plumbing, vents, ducts, air conditioning and heating equipment, and any o t h e r mechanical or electrical equipment shall be concealed from public view; and screened in a manner so as not to be visible from any angle or any height outside a building. The height of a parapet wall for screening purposes must be equal to or greater than the height of any mechanical equipment. Roof top communication antennae shall be camouflaged and/or stealth in design in accordance with Chapter 107 of the LDO.

5. All rooftop screening shall be part of the articulation of a building and not appear as an afterthought; shall be architecturally integrated and compatible with the architectural style.

D. BUILDING FACADES.

1. Commercial “storefronts” that reflect the architectural style of the building, balance window space to building wall space, and create display windows rather than floor to ceiling glass fronts is encouraged. Windows and doors shall be aligned and sized to bring order to the building façade and sufficiently recessed to contribute to the building’s energy efficiency and create facade patterns that add variety and visual interest to the building design.



2. Some element(s) of display windows, awnings, entry areas, colonnades and arcades shall be designed along the street frontage, plaza areas and along the pedestrian sidewalks.

3. In the event an arcade or colonnade is to be used along the front of a building as a primary pedestrian way, the arcade or colonnade shall be designed as an integral part of the overall architecture of the building; located and oriented to connect with adjacent open space areas of the development; and of sufficient height and width to accommodate the anticipated unobstructed pedestrian traffic generated by anticipated uses in the development.

4. All building facades must contain conspicuously placed street address numbers (refer to Chapter 109 of the LDO).

E. ADDITIONAL STANDARDS FOR TND DEVELOPMENT

1. The edges of a commercial area should blend into adjacent neighborhoods and/or the civic space through building forms, massing and architectural styles and without buffers. Parking lots and garage doors rarely front the street.

2. All commercial activities shall be conducted entirely within the enclosed commercial buildings with limited outside storage which shall be screened from public view with an opaque fence or decorative wall not to exceed six(6’) feet in height. Materials shall not be stacked, piled, or stored in such a manner as to project above the screen wall.

3. Outdoor patios and dining areas, seating areas, or small “vignette style” display areas are required to add to the pedestrian environment of the neighborhood.

4. The commercial buildings shall be designed in a manner that is more residential in scale and mass to be compatible with the residential neighborhood. Shopfront, Gallery, Fore/Courtyard and even Porch frontages are strongly encouraged and should provide a pedestrian connection to the sidewalk, street, or open space network (see Illustration 20).

5. Buildings in the “village core” shall be located close to the street, creating a well-defined outdoor room.

Gallery Porch Fore/Courtyard Shopfront

6. Consideration of Other Building Types in TND Developments

a. Vertically Integrated Mixed-Use: This building type is a small-to medium-sized structure, typically attached, intended to provide a vertical mix of uses with ground-floor retail, or service uses and upper-floor service, or residential uses. This type is an appropriate component of a TND neighborhood core but could be utilized within the residential parcels if carefully located and designed, thereby being a key component for providing neighborhood appropriate retail and/or services.

b. Live/Work: This building type is a small to medium-sized attached or detached structure that consists of one dwelling unit above and/or behind a flexible ground floor space that can be used for residential, service, or retail uses. Both the ground-floor flex space and the unit above are owned and/or occupied by one entity. This type is typically located within blended density neighborhoods or in a location that transitions from a residential neighborhood into higher intensity uses such as the neighborhood core. It is especially appropriate for incubating neighborhood-serving retail and service uses and allowing the TND neighborhood core to expand as the market demands.


A. EDGE TREATMENTS

1. All major new commercial development should include a pedestrian circulation system of active and passive open space areas designed, located and oriented to provide: high pedestrian accessibility within and around the development; connections to adjacent developments to enhance a structure of continuous open space throughout the community; and a buffer between less developed, less densely developed lands and urban development patterns.

2. Buildings located on the exterior of new projects adjacent to the undeveloped edge of the City shall maintain a low profile in terms of single-story height, bulk and massing; except in an urban environment.

B. TRANSITIONS

1. Structures within a multi-building development should be designed to transition into either the surrounding development or natural landscape; with the size, massing and height of the proposed structures relating to the prevailing scale of adjacent development.



3.7 OTHER CONSIDERATIONS.

1. The signage needs (both building mounted signage and freestanding signage) should be carefully considered for all of the buildings/tenants when developing the site plan, landscape plans and elevations for commercial centers.

2. Outdoor lighting shall be consistent and comply with the standards outlined in Chapter 107 of the LDO and Volume Two of this PED Manual when

applicable.



CHAPTER 4: BUSINESS PARK AND INDUSTRIAL LAND USES


A. GENERAL BUILDING SITE DESIGN.

1. Some limited Commercial land uses may be permitted in the Employment Character Areas as shown in the General Plan; in which case the development of such commercial land uses must be part of a business park development rather than a stand-alone commercial development.

2. Land uses permitted by the Business Park (BP) zoning, as delineated in Chapter 106 of the LDO, shall be developed as part of or within an approved planned business park development rather than as a stand-alone project.

3. Business parks shall be designed with an interior street system that takes its access from the major arterials (see Illustration 21 below). Proposed new major centers of employment and governmental offices shall plan and design their development to link directly with public transit stops when available or will be provided over time and when defined in the TIA for the development.

4. When industrially zoned parcels are developed with permitted industrial land uses, as delineated in Chapter 106 - Table 106-3 of the LDO, and developed as a stand-alone use they shall take direct access only from an arterial street that is appropriately scaled to serve commercial and freight traffic.

5. Subdivision design, site plans, and building design must reflect sensitivity to natural features of the site; including topography; adjacent uses and

development; and views of surrounding mountains.

B. SCREENING.

1. Trash and refuse collection containers: Shall be screened with a six foot (6’) solid masonry wall. Trash and refuse containers shall be located such that they are not the visual focal point of a driveway or parking area, or cannot be viewed from a public street. Those sites that can only locate the refuse containers in a highly visible location shall provide decorative latching gates, for screening the containers, at the opening to the enclosure.

2. Outside storage areas, work areas, and production areas: When permitted shall be limited to the rear or side yard (not front yard) and screened as outlined below. Materials shall not be stacked, piled, or stored in such a manner as to project above the screen wall.

a. When adjacent to any roadway the screen wall shall be a solid masonry wall, not to exceed eight feet (8’)in height, located within the lot at the building setback line (not along the property line). Exceptions to this locational requirement may be made when the business park or industrial subdivision is platted with a landscape tract, not less than thirty-five feet (35’) in width, adjacent to the roadway in which case the screen wall may be placed at the rear and/or side lot line.

b. When adjacent to residential, mixed-use, office, or commercial land uses the screen wall may be located along the shared property line with the required setback area behind the screen wall. The screen wall shall be a solid masonry wall at least six feet (6’) but not to exceed eight feet (8’) in height. The City may require the screen wall to be placed at the setback line, rather than on the property line, if it is determined that public access to an existing or planned public open space system would be prevented if the wall were placed at the property line.

c. When a business park parcel/lot is adjacent to other business park parcel/lot, a solid masonry wall, not to exceed eight feet (8’) in height, may be located at the side and rear property line.

d. When an industrial land parcel/lot is adjacent to another industrial land parcel/lot, a fence, not to exceed eight feet (8’) in height, may be located along the shared property line.

3. Parking areas: When in front of the building and/or adjacent to a street the parking area shall be screened from public view by a solid three foot (3’) high screen wall that is decoratively treated to match the architectural style and design of the development or a three foot (3’) high landscape berm or combination thereof. Parking areas shall not encroach into the required front yard and the screen wall shall be located at the front building setback line. The side yard screening wall may be located along the side property



line. The screen wall shall be a minimum three feet (3’) back of the parking surface area to accommodate for vehicular overhang.

4. All solid masonry walls intended for screening functions shall be decorative having an architectural texture, color and finish compatible with the primary building; with the finished elevation exposed to the public view or adjacent property.

C. PARKING DESIGN

1. Parking lots for major employers, government offices, and businesses within a business park development that contain over one hundred and fifty (150) spaces should be designed with electric re-charging stations, and solar panel shade structures.

2. Parking lots shall be designed to utilize rainwater harvesting techniques by sloping the parking lot surfaces to direct the stormwater runoff into landscaped bioretention planters within and/or along the perimeter of the parking lot. The bioretention landscaped planters may be designed as: raised flow-through planter boxes; flush in-ground planter boxes; or below grade planter boxes. Use curbstop sections, formed curb with curb openings, or flush curbs to stop car tires but allow water to flow into the planting areas.


A. Unless otherwise determined by the City’s Traffic Engineer, all development projects are required to provide a Traffic Impact Analysis (TIA) prior to receiving approval; with specific emphasis on the impact of truck traffic on adjacent development, the internal circulation system of the proposed development, and the appropriate development of transit amenities.

B. Proposed new business park developments and major industrial employment centers shall provide transit related site design features and amenities such as, but not limited to, shelters, benches and lighting (see Illustration 22 below).

C. Multimodal connections between workplace uses and abutting support uses such as retail and service commercial establishments is encouraged and should include drive, walkway, and trail connections.




A. Design the required landscaping to;

1. Utilize, to the greatest extent possible, harvested stormwater; and

2. Strategically locate appropriate plantings to cool buildings and shade parking lots; and

3. Provide both visual screening and land use buffering; and

4. Improve the aesthetics of the development as seen from public view.

B. Landscape should be fully integrated with the building mechanical systems such that air conditioning condensate collection may be used directly by the landscape or directed into a cistern system; and building roof drains and downspouts whether exposed or integrated within the building walls shall be directed to landscape areas adjacent to the building where it can be stored and used to irrigate the plants or infiltrated into the ground. Foundation planting shall be required along all building elevations that are visible from the public street and may utilize the plant palette listed in Appendix C herein.

C. All required on-site parking lots shall provide landscaping along the perimeter of the parking lot and within the parking lot utilizing the plant palette listed in Appendix B herein and in accordance with Chapter 107 of the LDO.

D. The landscape strip, all required front building setbacks, and those setback areas in front of a screen wall shall utilize the plant palette listed in Appendix B herein. Street trees shall be planted in a regularly spaced lineal pattern of single or alternating species with shade canopies of a height that at maturity clears at least one story.

E. All other required yards that are open areas (outside of screened storage areas, work areas, and production areas or boundary line walls) shall be landscaped utilizing the plant palette listed in Appendix C herein.

A. GENERAL ARCHITECTURAL STANDARDS.

1. All buildings shall provide architectural detailing on all exterior elevations (360° architecture); not just the front elevation. Window embellishments shall be provided by adding architectural features that enhance the elevations (e.g. greater variation of window design, different window styles, tile inlays and recesses, structural pop-outs, gabled roof features over the windows, etc.).

2. For all buildings the mechanical equipment and similar utility devices, whether ground level or roof mounted, shall be screened from public view and designed to appear as an integral part of the building; except for solar panels. The mechanical equipment screening shall be included in the overall building height. Mechanical equipment shall be treated to be non-reflective.

3. Service and loading bays shall be oriented away from adjacent residential and mixed-use zoning districts and to the greatest extent possible should not front onto or be visible from the public street. For those sites that can only locate said activities in a highly visible location screening be a method approved by the City may be required.

4. Buildings shall be designed to facilitate the efficient use of energy through building orientation, window and door placement, awnings, canopies, window treatments and other appropriate design solutions.

5. Building orientation and building design shall address and mitigate the negative impacts of noise, odor, or dust that may be generated from a building and/or land use of any Business Park or Industrial development.

B. BUILDING MATERIAL AND DETAILS

1. Reflective building materials are prohibited. Mirrored surfaces or any treatment that changes ordinary glass into a mirrored surface are prohibited. Metallic surfaces, including roof materials, shall be chemically treated to be non-reflective.

2. Color should be used to accent entryways and special architectural features of the building rather than color bands of corporate identity.

C. ROOF ARCHITECTURE.

1. Full roof architecture utilizing simple and varied roof forms shall be required for all new business park and industrial development; while long, continuous mansard roofs, false mansard roofs, large expanses of flat roofs and veneer (false-front) parapets are discouraged. Parapet walls shall be designed and constructed in a manner to appear as a solid, three-dimensional form rather than a veneer.



2. All rooftop screening shall be part of the articulation of a building and not appear as an afterthought; shall be architecturally integrated and compatible with the architectural style.

3. Roof access shall be from within the building.

D. BUILDING FACADES.

1. Windows and doors shall be aligned and sized to bring order to the building façade and sufficiently recessed to contribute to the building’s energy efficiency and create facade patterns that add variety and visual interest to the building design.

2. All building facades must contain conspicuously placed street address numbers (refer to Chapter 109 of the LDO).


A. Non-vehicular connections to adjacent developments through shared and/or aligned retention areas, multimodal trails, and open space areas are to be made by the Employment land uses whenever available and/or when designated for such future connectivity by the Surprise General Plan or the Parks and Recreation Master Plan.

B. Development of subdivisions within the Business Park and Industrial zoning districts shall provide a landscape buffer strip, as outlined in Chapter 106 and Chapter 108 of the LDO, along the perimeter of the development on a subdivision basis rather than encumbering the individual lots within the subdivision with the buffer area requirement.

C. When developed as a stand-alone industrial land use adjacent to the undeveloped edge of the City or to an existing residential development the industrial development shall be responsible for providing the required buffer area for the development.

D. Buildings located on lots along the perimeter boundary of a business park and/or industrial subdivision that are adjacent to the undeveloped edge of the City or to an existing residential development shall maintain a low profile building in terms of single-story heights not to exceed twenty-five feet (25’). Building heights above twenty-five feet (25’), up to the maximum building height allowed per the zoning district, may be achieved by increasing the building setback adjacent to the perimeter boundary as outlined under the specific zoning sections of Chapter 106 of the LDO.



CHAPTER 5: ENVIRONMENTALLY SENSITIVE LANDS STANDARDS


A. The City of Surprise requires responsible development, the preservation of natural habitats for flora and fauna, and the conservation of environmentally and culturally sensitive lands and resources. Sustainable and creative development is encouraged with the goal being to fit development into the natural site with minimal intrusion, and to be sensitive to adjacent uses. For this reason any property that possesses characteristics which would support their identification as cultural resources or having environmentally sensitive features shall utilize an integrated conservation design approach to development and assure compliance with the Environmentally Sensitive Lands and Cultural Resource Standards set forth in this section and those in Chapter 104 of the LDO as a part of any development

submittal.

B. INTEGRATED CONSERVATION DESIGN APPROACH. An integrated conservation design is vital to reducing fragmentation of both habitat and wildlife movement areas, improving community character, and protecting both environmentally sensitive features and cultural resources. Regardless of the acreage or zoning, when any portion of a development site is determined to be in an area with environmentally sensitive features or cultural resources the entire development site shall be required to utilize an integrated conservation design approach and develop an Environmental Inventory Plan (as described in Chapter 104 of the LDO). The development shall provide the City with a development plan rooted in this integrated design approach and based on the Environmental Inventory Plan. The following 4-steps are involved when developing any project using this integrated conservation design approach. For subdivisions theses design steps occur in an order opposite that of conventional subdivisions.

1. Identify Conservation or Preservation Areas. The first step is identifying areas of the property to conserve or preserve. This is done by completing an “Environmental Inventory Plan” (detailed in Section 104-2.2 of the LDO) that delineates the location of all environmentally sensitive features, cultural resources, and the associated buffer areas. Also, identify the location of any additional open space required to satisfy the zoning requirements for the development; keeping in mind the potential to create areas and connections beyond the boundaries of the proposed development to maximize the benefit to wildlife and residents alike.

Example Site Before Development

Integrated Conservation Design identifies the environmentally sensitive features & cultural resources of the site before drawing lot lines & roads.



2. Select Building/Housing Locations. Select building/housing sites to complement the location of the environmentally sensitive features, cultural resources, and open space. Designing the lots around these conserved spaces ensures that each occupant/resident can take full advantage of these conserved common areas. Utilizing a cluster development design may make this simpler to achieve but it is not required.

3. Connect the Dots. Draw in a multimodal network of streets and trails that connect the development to existing roads and, if possible, regional trail networks or public greenways.

4. Draw in the Lot Lines. Finally, draw in the individual lot lines.

C. ESTABLISHMENT OF BUFFER AREAS. The buffer areas required by Chapter

104 of the LDO shall be designed to achieve the following performance standards:

1. Protect the biological function and enhance wildlife use of any natural habitat identified by the Environmental Inventory Plan for the development site.

2. Minimize and, to the greatest extent possible, mitigate the anticipated impacts of development to environmentally sensitive features and cultural resources.

The cluster subdivision (right) accommodates the same amount of development as its conventional counterpart (left); in this example 32 lots. The difference, however, is that the cluster design provides that more than half of the site is retained as preserved or open space, a permanent amenity shared by all property owners. Conventional development gives each owner a large lot surrounded on all four sides by neighbors whereas the cluster design provides each resident an uninterrupted view of the surrounding landscape and access to preserved communal open space within the development.

Conventional Development vs. Cluster Development



3. Enhance the integration of development with the site by preserving existing site topography, including but not limited to, such characteristics as: hillside areas, steep slopes, ridgelines, significant rock outcroppings, and existing drainage and water features.

4. Preservation of significant stands of vegetation and communities of protected native plant(s) within and/or adjacent to a development site.

5. Prevent unnecessary and adverse impact upon species utilizing special habitat features, including nest and/or den sites, night roosts, key feeding areas, wintering and/or production areas as identified by the Environmental Inventory Plan.

6. Preserve and enhance the existence of wildlife corridors and wildlife movement between natural features, through and adjacent to the development site.

7. Provide appropriate areas for passive human access to the site’s natural habitats, environmentally sensitive features and cultural resources.

D. GENERAL SITE DESIGN.

1. Projects in the vicinity of large natural habitats and natural habitat corridors shall be designed to complement the visual context of the natural habitat. Techniques such as architectural design, site design, the use of native landscaping and choice of colors and building materials shall be utilized in such a manner that scenic views across or through the site are protected, and that manmade facilities are screened from off-site observers and blend with the natural visual character of the area (see Illustration 23 below). These requirements shall apply to all elements of a project, including any aboveground utility installations.

2. Projects shall be designed to minimize the degradation of the visual character of any environmentally sensitive feature(s) within the site and to minimize the obstruction of scenic views to and from those features within the site.

Illustrative Example: Building siting respects the topography of the area.

ILLUSTRATION 23



3. The greatest amount of development and the highest densities of housing should occur in the flat land (under five percent (5%) slopes). Irregular terrain with irregular slope conditions and hillside lands (over ten percent (10%) slopes) shall be larger lot residential with a building envelope delineated to insure building/site integration and to reduce the impact of development to the hillside.

4. Mass grading is prohibited in the hillside development area. Mass grading shall be limited or prohibited for other lands within the environmentally sensitive areas of the City where damage to existing vegetative cover, washes and drainage patterns might occur.

5. Wherever possible, but particularly in hillside development areas, site plans and designs should reflect a sensitive approach to development wherein roads, hiking and equestrian trails, access walkways, driveways and drainage areas conform as closely as possible to the natural contours of the site.

5.2 WALLS: PERIMETER, PRIVACY AND RETAINING

A. PERIMETER WALLS

1. Perimeter walls or fences shall follow the contour of the natural terrain and be “open” in design where a wall abuts an open space area, buffer area, or environmentally sensitive feature. Walls or fences shall be a maximum of six feet (6’) in height with no more than three feet (3’) being constructed of a solid or opaque material. That “open” portion of the wall or fence may not include chain-link or wood materials (see Illustration 24 below). Notwithstanding the foregoing, walls exceeding six feet (6’) in height and constructed of solid or opaque material may be approved by the Community Development Director if the wall is for the purpose of screening non-residential uses.

2.

Perimeter walls and fences surrounding a lot, tract, or subdivision within a hillside development area shall be prohibited; only privacy walls and retaining walls may be permitted as outlined below.

ILLUSTRATION 24

Perimeter walls shall follow the contour of the natural terrain.



3. Within the ten to fifteen percent (10-15%) slope category of a hillside development area, exceptions to the above prohibition on perimeter fences or walls may be permitted. In those instances where an exception is desired, applicants shall submit a detailed Wall Plan to the Community Development Director for review and action. In conjunction with the submittal of the Wall Plan to the Community Development Director, the applicant shall submit a copy of the Wall Plan to the appropriate City department(s) for review and approval for conformance with all City grading and drainage requirements. Wall Plans shall indicate the proposed locations of walls or fences, the proposed materials, colors and design of any wall or fence, and fence construction and disturbance mitigation measures. Such plans shall be accompanied by a narrative explaining the reasons why such an exception should be made. Wall Plans may be approved by the Community Development Director upon a finding that the proposed location and design of the wall(s) will not be contrary to the intent and purpose of the Environmentally and Culturally Sensitive Land Developments Standards.

B. PRIVACY WALLS

1. Fences or walls on lots within a hillside development area shall be restricted to privacy walls attached to or directly screening a portion of the main residence. Privacy walls shall not exceed six feet (6’) in height, shall be architecturally compatible with the main residence and shall be limited to the building envelope area only.

2. Privacy walls shall not be erected on a retaining wall and shall be offset a minimum of four feet (4’) when utilized unless the combined height of the walls does not exceed six feet (6’).

C. RETAINING WALLS

1. The design of all retaining walls shall be prepared by a registered engineer or architect and shall be designed to blend with the surrounding environment and/or development in color, materials and style.

2. No first-tier lots shall have a side or rear yard retaining wall exceeding six feet (6’) in total vertical wall height in any residential district or ten feet (10’) in a non-residential district.

3. A single retaining wall in any front yard shall not exceed four feet (4’) in height in residential districts or six feet (6’) in height in non-residential districts.



4. Retaining walls of over four feet (4’) in height shall not be placed at the property line.

5. Additional retaining height may be achieved through the use of offset retaining walls and terraces: such walls shall be offset a minimum of four feet (4’) and all terraces shall be landscaped appropriately for the width of the offset (see Illustration 25). Retaining walls shall incorporate weep holes for drainage and sleeves for irrigation.

6. The total vertical wall face (including view fencing) visible from any street, adjacent property line or publically-accessible open space for any single lot shall not exceed twenty-five feet (25’) in height. Terraced walls shall be constructed with decorative products and terraces shall be landscaped to minimize their visual impact.

5.3 ROADWAYS

A. Rather than transforming the area, the roadways shall follow the natural topography of the area with the roadways designed to minimize excavation and embankment scars and the overall amount of land disturbance. The City prefers the use of curvilinear horizontal alignments and gently rolling profiles consistent with the natural topography to minimize unnecessary disturbance to the existing environment (see Illustration 26).

B. Additional rights-of-way may be required for cut or fill slopes, bike paths, horse trails, traffic control devices, fire hydrants or other public facilities located adjacent to streets. Where cut or fill slopes extend beyond the rights-of-way, a permanent easement may be provided in lieu of increasing the width of the rights-of-way.

5.4 WATER FEATURES

A. NATURAL WASHES and FLOODWAYS.

1. County Floodways and FEMA designated washes that traverse and/or are adjacent to a development site shall be assimilated into a linear open space system that is integrated into both the development’s and the community’s open space system. A seventy five foot (75’) buffer area shall be required along the perimeter of these floodways and washes. Within the required seventy-five foot (75’) buffer area, associated with and adjacent to these types of floodways and washes, paths for both pedestrians and bicycles and if applicable equestrian trails are encouraged and may be required to be developed as an amenity by the developer (see Illustration 27).

2. Naturally occurring ephemeral desert washes identified by the Drainage Report shall, as much as possible, be retained in their natural condition with buffer areas established as natural area open space and with development setback the appropriate distances necessary to allow the wildlife corridors to remain uninterrupted (see Illustrations 28). Specific buffer area dimensions to be determined by the City in consultation with Arizona Game and Fish.

3. Disturbance to larger ephemeral washes shall be limited to that required for road and utility crossings only. The uses of bridges and culverts should be considered for such crossings where their use would cause fewer disturbances to the washes. Disturbed areas shall be revegetated using indigenous vegetation.

4. The City may grant open space credit (at a 1: 1.25 ratio) for habitat restoration of and along those ephemeral washes that have been identified by Arizona Game and Fish as being missing links/sections in important wildlife corridors. (see Illustrations 29)

5. Drainage basins, retained washes, and new drainage channels shall be given a “natural” desert character. Native materials in the construction of all storm water features (ie. basins, channel bottoms, and headwalls) must be used. Terracing, berming and contouring is required to naturalize and enhance the aesthetics of all drainage basins, retained washes, and channels. Basin slopes shall comply with Engineering Development Standards.

6. Trails will be permitted within these corridors, but motorized vehicles would be prohibited.

5.5 TRANSITION STANDARDS AND EDGE TREATMENTS

A. On sites where there is significant change in the grade levels from the site to adjacent properties, the site design should accommodate the grading transition through design techniques such as landscaped terraces, landscaped slopes of 4:1 (run-to-rise) or gentler, or some similar gradual technique.

B. When the site has a non-residential use and the adjacent site is a residential use, required screening walls should either be placed along the edge of the parking/driveway areas if the developing site is higher than the adjacent residential site, or at the property line if the site is lower.

C. Hillside development shall receive edge treatments that soften the appearance of an abrupt transition between the built and natural environments. Such treatments shall consist of alternative perimeter fencing (adobe, native stone or vegetation etc.), offset, or staggered rear lot lines, transitional landscaping or other similar elements intended to soften the transition.

ILLUSTRATION 29



5.6 HILLSIDE DEVELOPMENT AREA

A. Those lands considered to be in a hillside development area (ten percent (10%) or greater) shall be limited in the density permitted based on the slope bands of the property as further delineated in Chapter 104 of the LDO.

B. Slopes that are fifteen percent (15%) and greater are considered to be steep slopes and development shall be highly restricted.

C. The grading concept for any site shall seek to balance cut and fill on the site to avoid off-site stockpiling and further damage to the natural topography.

D. Significant rock outcroppings, ridgelines and unstable slopes need to be identified and conserved. Incorporate such features as an inclusive element in the overall design of the development rather than isolated and inaccessible.

E. All site plans and designs should utilize topographic maps that reflect the existing terrain, including: contour intervals (at a maximum of 10 feet), and variations in, the site terrain; elevation of critical spots; rock outcrops and special characteristics of the site.

F. All structures located within a hillside development area shall blend naturally into the landscape through the use of materials and colors compatible with the natural earth colors of the ridgeline area, rather than stand out as a prominent focal point.

G. Multilevel buildings, as well as all rooflines of buildings, shall follow the general slope of the site in order to keep the building height and profile in scale with surrounding natural features (see Illustration 30).

A.

Adaptive Reuse: The conversion of historic or obsolescent building(s) from their original or most

recent use to a new use representing compatible and appropriate change.

Apartment Complex:

Archeological Resource: Any material remains of past human life or activities that are of historic or pre-historic significance. Such material includes, but is not limited to, pottery, basketry, bottles, weapons, weapon projectiles, tools, structures or portions of structures, pit houses, cultural landscapes, rock paintings, rock carvings, intaglios, graves, skeletal remains, or any piece of any of the foregoing items (see cultural resource herein).

The programming of events may include local public and charter schools, public and private universities, local athletic clubs, and other competitive organizations. A city-owned aquatic center may, at the discretion of the Parks and Recreation Department Director, be open to the general public during times when not scheduled for competitive events or related practice times. The facility may also be programed for city-sanctioned aquatic classes.

B.

Berm: A mound of earth that is used to shield, screen or buffer undesirable views, separate incompatible land uses, provide visual and landscape interest, decrease noise, or control the direction of water flow.

Bicycle Circulation System: Multi-use pathways and on-street bicycle lanes combine to provide

a comprehensive means by which bicycles can travel within and through the City.

Bollard: A thick, low, architecturally, designed vertical post, or a series of vertical posts, that are

placed to help define, or border, pedestrian and/or bicycle paths.

Buffer Area: An area of land retained in its natural state which protects and/or surrounds an environmentally sensitive feature or cultural resource with the purpose of mitigating any potentially negative impacts to the feature or resource.

Buffering: The technique of providing landscape or other improvements on land set aside or in a buffer area used to separate different intensities and types of land use.

Wildlife Corridor: Pathways or habitat linkages that connect discrete areas of natural open space otherwise separated or fragmented by topography, changes in vegetation, and other natural factors in combination with urbanization, and which 1) permit animals to move between remaining habitats allowing depleted populations to be replenished and promoting genetic



exchange; 2) provide escape routes from fire, predators, and human disturbances, thus reducing the risk that catastrophic events, such as fire or disease, will result in population or species extinction; 3) serve as travel paths for individual animals as they wander throughout their home ranges in search of food, water, mates, and other needs, or for dispersing juveniles in search of new home ranges.

Wildlife Habitat: Locations where native wildlife has a tendency to congregate due to provision

of food, shelter and/or water.

APPENDIX C – LOW WATER USE DROUGHT TOLERANT PLANT LIST

This list does not include all of the possible low water use drought tolerate plants approved for the Phoenix Active Management Area; rather it lists those plants that the City of Surprise would prefer a homeowner/property association to use within areas they maintain and for private homeowners to use on-site. The use of other indigenous low water use drought tolerant plants may be permitted. However, the use of plants which are known to be invasive to indigenous vegetation shall be prohibited.

It is strongly recommended that homeowners check with their neighborhood’s landscape covenants before designing their private landscaping.
